USB Port Standard USB connector for the setup and control of a DMTH4 from an Windows 2000 or Windows XP computer system with USB interface. Status LED The DMTH4 is normally configured as the end slave unit in a DM Series stack. In this configuration, the Status LED glows steadily when power is applied and a Master unit has been detected. The STATUS indicator will blink to indicate that it has not found the Master unit or some other error exists. Rear Panel Note: The DMTH4 is shipped from the factory configured as a Master unit. In this mode, the Status indicator glows steadily when power is applied. Mode Switch If a unit configured to run in Slave mode doesn t detect a master unit on powerup, it will refuse to boot up and the Status LED will blink rapidly. In this case, pressing the Mode switch will force the unit to boot up temporarily in Master mode to allow settings to be examined or changed. Cycling the power returns the DMTH4 to Slave mode. Pressing the Mode switch while powering up the DMTH4, places the unit in Software Update mode. The Status LED blinks slowly while the firmware is updated, then extinguishes when the process is complete. Cycling power exits Software Update mode.

7 Installation Guide Hardware Installation Installing the DM system into a rack The DMTH4 occupies a single space. There are no special ventilation requirements. Mount with 4 rack screws using the appropriate mounting holes. It is recommended to use nylon washers to prevent damage to the front panel s finish when tightening the screws. For North American installations, connect the Power Cable supplied with the unit between the DMTH4 and a stable power source. All DM processors have internal switching power supplies that can tolerate voltages ranging from 100 VAC to 240 VAC. Use an approved power cable for installations outside North America. Cables It is recommented to use lacing bars for cable strain relief when mounting in a rack. Use only professional audio cable with proper shielding - typically, two conductor plus ground/shield. Audio Connections The analog audio inputs and outputs are connected through 5 pin de-pluggable connectors. Strip the insulation back 1/8 to 3/16 but do not tin (apply solder to) the leads. Insert the wire into a de-pluggable connector, leaving less than 1 mm of bare wire exposed, then tighten the retaining screw. Caution: Do not over tighten the retaining screw. Retaining Screw (Do not overtighten) 5-pin depluggable connector Audio Inputs (AUX and CODEC) Unbalanced Sources Unbalanced audio sources (positive and ground) include items such as consumer VCR s, DVD players, etc., and may use both two wire and three wire cables. In either case, the positive output from the source should be connected to the appropriate positive (+) input on the DMTH4. The shield or negative ( ) output should be connected the DM s negative ( ) input. Two wire cables should have a jumper between the DMTH4 negative input and ground. Three wire cables should have the shield connected to the DMTH4 s ground input and the shield and negative ( ) leads joined together at the unbalanced source end. Source + Shield DM In + - Unbalanced source to DM input (3-Wire) Source + Shield DM In + - Unbalanced source to DM input (2-Wire) Do not apply solder to leads Do not leave more than 1 mm of exposed wire beyond the connector. Balanced Sources Balanced differential sources from external equipment and microphones should be wired according to Balanced source to DM input (3-Wire). (See illustration.) When connecting balanced sources to the DMTH4, it is important to not connect chassis ground (shield) to either signal conductor. Note the labeling on the DMTH4 Chassis for the positive and negative leads. Ground is shared between two connections (the center pin). Note: The DM Series does not have a pin 1 problem. Inputs and outputs are true differential connections. Source + - Shield DM In + - Balanced source to DM input (3-Wire) Rio Rancho, NM 7

8 DMTH4 Audio Outputs (AUX and CODEC) The AUX and Codec outputs are a balanced differential configuration and include an attenuator to reduce the signal to mic level.

See the Rear Panel Ctrl tab in the Control Panel software Help for setting all programmable input parameters. Programmable Outputs Programmable outputs are used to indicate the current state of a programmable input, monitor activity on telephone or codec interfaces, and monitor active preset changes. Each programmable output is the electrical equivalent of a contact closure to ground. When a programmable output is active, it conducts current to ground. When the programmable output is inactive, no current flows to ground. The maximum usable voltage for the programmable outputs is 40 V and they will safely conduct up to 100 ma DC continuous. Following are some typical uses for the programmable outputs. LED is on when the programmable output is active +5VDC (from Programmable I/O Pins 14, 20, 25) 380 Ohms Programmable Inputs Programmable inputs are provided to enable external control over a variety of parameters. Each input can respond to a contact closure, a DC voltage source, or the variable voltage output from a potentiometer. The following illustrates common connections to the programmable input pins. (See also Programmable Inputs and Outputs Wiring Example.) No external pull-up resistors are necessary because each programmable input is internally pulled up through a 100K resistor to +5V.

14 R TELEPHONE HYBRID INTERFACE MODE STATUS USB POWER DMTH4 Network - One or more DMTH4 devices may be made available for network connections by connecting them to a gateway computer system. A gateway PC, or gateway server acts as a middleman, receiving commands for a DMTH4 over a network connection, and forwarding them to the DMTH4, which is connected to it via USB. To work as a gateway server the PC must be a member of some local area network (LAN) or the internet, by means of an Ethernet connection, and be running the Lecnet2 Net Server program. Extron IPL T S - One or more DMTH4 devices may be made available for network connections by connecting them to an Extron IPL T S ethernet control interface. The IPL T S interface acts as a middleman, receiving commands for a DMTH4 over a network connection, and forwarding them to the DMTH4, which is connected to it via an RS232 port. To work as a gateway server the IPL T S interface must be a member of some local area network (LAN) or the Internet, by means of an Ethernet connection. Serial->COM1 - An serial port for RS-232 communications between the DMTH4 and the computer. The DMTH4 leaves the factory configured as a Master unit to facilitate initial setup. If the unit has been configured as a slave, it can be temporarily set to Master mode via the front panel MODE button. If the front panel MODE button is used, the unit will return to Slave Mode the next time the DMTH4 power is cycled. MODE Button Using the DMTH4 Control Panel to Change Master/Slave Mode Changing the Master/Slave Mode can be easily accomplished through the DMTH4 Control Panel. To do this, select Connect on the DMTH4 Control Panel Menu Bar, then click Connect >USB to open the Select Lecnet2 Device dialogue. Highlight the DMTH4 and click OK. Note: The control panel will list any COM ports available on the computer system. Serial->COM2 - Same as above.

The DMTH4 can be configured on site or a configuration file can be created in advance, then downloaded into the unit in the installation. The minimum required setup to pass audio includes: Inputs, Matrix and Out Source. Input and output filters and compressors are used to tailor the system for specific audio situations. Master/Slave Configuration When stacking multiple DM Series units, one unit is always set as the Master and all subsequent units are set as Slaves. The DMTH4 is normally configured as a Slave unit and placed at the end of the DM Series chain. Inputs Matrix Out Source Connecting to DMTH4 through USB 14 LECTROSONICS, INC.

15 Installation Guide WIth the DMTH4 connection configured, it is now possible to set the Master/Slave operating mode. This is done by selecting Device Setup from the Control Panel Menu Bar. Select Expansion Mode from the drop down menu and select Slave. Setting Master/Slave Mode Initial Setup Hints 1) Right clicking the mouse is powerful in this interface. You can activate quick access to a number of setup functions (for example - right click in any input box in the INPUTS tab). It also allows some powerful cut and paste capabilities - especially in the matrix setup and the filter (both input and output). 2) Store startup settings in a startup default preset. (See Storing and Recalling Presets in the online HELP.) 3) Presets will take about 4 seconds to switch due to the many parameters in the unit - audio will switch off temporarily during a preset switch to avoid feedback. If you need quicker response with no interruption to the audio, use macros instead - try using the macro recorder for making any changes. The only changes that cannot be made in a macro are filter adjustments. 4) Store presets after changes are made and not before they are made. 5) Help is always available by clicking Help on the Main Menu Bar. This Help is a comprehensive resource and includes the latest revisions to the software and firmware. IMPORTANT: Any changes made during setup must be saved in the unit via the preset menu. For direct support from the factory, call (800) Ask for anyone in the SALES department. They will be able to answer your setup and/or technical questions or will get the correct person who can help on the phone. Rio Rancho, NM 15

16 DMTH4 Example Teleconferencing Setup Link Conference Rooms with a DMTH4 Example Setup The following information describes setting up a DMTH4 to connect two locations for a conference. The DMTH4 is designed to be part of a DM Series chain. In this example, the DMTH4 is a slave unit to a DM1624 Series Automixer. This example also assumes that the hardware has been installed and is operating properly. Conceptually, the setup has two conference rooms, each with two microphones and two ceiling mounted speakers connected to a DM1624 in a Mix-Minus configuration with a DMTH4 linking the rooms together via a telephone connection. (See Link Conference Rooms with a DMTH4, Example Setup.) The actual process to create the signal path so all members of both conference rooms have the ability to hear and be heard all other members in the conference rooms requires four simple steps: setting up the DMTH4 Main Matrix, setting up the DM1624 Main Matrix, setting up the DM1624 Expansion Matrix and setting up the DMTH4 Output Source Multiplexer. This is illustrated in Conference Room Signal Flow Diagram. In 1 In 2 In 3 X X Out 1 Out 2 Spkr 1 Spkr 2 DM Series Automixer (DM1624 Shown) Main Matrix Exp.

17 Installation Guide The following are assumed: A POTS line has already been connected to the DMTH4 rear panel Telephone Line jack The DMTH4 has been connected to the DM1624 via the DANI bus The microphones and overhead speakers are already connected to the DM1624 in a Mix-Minus configuration. The result will be that when a person talks into Mic 1 in Conference Room 1, they will be heard both in Conference Room 1 and in Conference Room 2. Likewise, if a person in Conference Room 2 talks into one of the microphones in that room, they will be heard both Conference Room 2 and Conference Room 1. The following discusses setting up a DM Series consisting of a DM1624 Digital Automixer and a DMTH4 Digital Telephone Hybrid on near end of the telephone connection. The same process is used to set up the DM Series at the other far end of the telephone connection. Setting up the DMTH4 Main Matrix The TEL Input needs to be configured so that it is connected to DANI Bus Mix Busses 1 and 2. (See Conference Room Signal Flow Diagram.) 1.) Select the Matrix Tab in the DMTH4 Control Panel, then select the Main Matrix sub tab. Right click the TEL input to Mix Bus 1 crosspoint and select Enable Crosspoint from the popup menu 2.) Repeat Step 1 for Mix Bus 2. Matrix Tab Setting up DMTH4 Main Matrix Click on Crosspoint Button audio and audio from Conference Room 2 are heard on the speakers in Conference Room 1. (See Conference Room Signal Flow Diagram.) 1.) Select the Matrix Tab on the DM1624 Control Panel, then select the Inputs to Outputs sub tab. 2.) Right click the Input Channel 1 to Output Channel 2 crosspoint and select Enable Crosspoint from the popup menu. Inputs to Outputs Tab Matrix Tab Input Channel 2 to Output Channel 1 Input Channel 1 to Output Channel 2 3.)
